Refinance Seller Note w/ SBA Loan

Hey everyone! I have a (hopefully!) quick question for anyone with some experience on the topic. Is it possible to refinance a seller note used for an smb acquisition with an SBA loan given the following scenario? Seller note terms: • Use of proceeds: acquisition only • Term: 4 years • Rate: 6% • Payment schedule: o Relatively small (less than the total interest that would be accrued annually) interest-only payments paid monthly for the first 2 years o Interest-only payments step up in years 3 and 4 o Balloon payment at the end of year 4 I would be looking to refinance the seller note somewhere between years 2-4. From my understanding this would be fine. Here is the language from the SBA SOP###-###-#### : “To be eligible for refinancing, any seller-financed note must have been in place and current (not on standby) for at least 24 months following the change of ownership.” It does not say anything about how much the payments need to be or if the payments need to include principal. Thanks, Nick
